CULTIVATOR.

Specification of Letters Patent.

Application filed August 12', 1912. 7 Serial No. 714,688.

To all whom it may concern Be it known that I, JOHN B. BONNEAU, Jr., a citizen of the United States, residing at Millsap, in the county of Parker and State of Texas, have invented certain new equipped with novellocking means for holding the shovel shanks therein. 7

The invention also aims to generally improve cultivator cross heads, the method of securing the shanks to the same and the method of securing the shovels to'the shanks. I

provide the spring latches 29 and 30 which ;are formed of flat spring metal and pivot- With these and other objects in view as shall become apparent as the description proceeds, the invention consists in certain constructions and. arrangement of parts as I shall hereinafter fully describe and claim.

For a complete understanding of my i-nvention reference is to be had to the following description and accompanying drawing, in which,

Figure l is a side elevation of my improved cross head and foot piece. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical section on the plane of line 33 in Fig. 2. Fig. 4 is a detail sectional view on the plane of line 4-4 in Fig. 1.

Referring to the drawing by numerals, 1 designates a gang beam which is connected to a cultivator by any suitable means cooperating with the jaw 2. A U-frame having the rigid arm 3 and the movable arm 4 is formed on the rear end of the gang beam 1. The movable arm 4 is pivotally secured to the beam 1 by the pin 5 which passes through the side plates 6 formed integrally with said arm. These plates 6 engage the sides of the beam and prevent lateral movement of the arm. To look the frame in its closed position I provide the bolt 7 which extends vertically through the arms 3 and 4 and has a nut threaded on its lower end.

A cross head or shank holder 8 is pivotally held intermediate of its ends between the U-frame by the tapering lugs 9 which fit into sockets in the arms 3' and 4. The

cross head is provided on one side of its vertical center with a plurality of horizontal slots 10 and on the other side with a plurality of vertical slots 11 all of which extend entirely through said beam.

The plow shank 12 adapted for use in the vertical slots 11 is straight and is provided on its inner edge near the upper end thereof with a plurality of notches 12 the purpose of which will be explained later.

A foot-piece 13 is bolted or secured in any ;desired manner to the lower end of the shank 12 and retains the'shovel 14 in position.

The shank 28 which is used on the side 10f the cross head having the longitudinal slots 10 is curved as shown and is provided j on its lower end with a foot-piece and shovel v similar to the ones described.

:To look the shanks in the cross head I ally secured at their inner ends to cross head. Each securing member 31- passes through a sleeve 32 formed on the inner end of each latch. Hooks are formed on the outer ends of the latches 29 and 30 by bending the said ends at an angle to the same as at 33, then inwardly as at 34 and then coiling them to form the loops 35. These hooks engage over the beveled flanges 36.

-A slot 37 extends longitudinally of the top of the cross head 8 over the horizontal slots 10 and allows a flange 38 on the latch 29 to engage the walls of the notches 12 in the curved shank 28 to hold the shank in position. A slot 39 similar to the slot 37 is formed on the rear face of the cross head and allows the flange 40 on the latch 30 to engage with the notches 12 in the shank 12. The plurality of slots 10 and 11 make it possible to vary the distance between the shanks.

From the foregoing description in connection with the accompanying drawing it will be seen that I provided a cross beam of simple construction in which plow shanks Patented Nov. 13,1913.

may be easily and quickly secured by spring latches. 7

What I claim is 1. A device of the character described comprising a beam, a cross head secured intermediate of its ends to said beam, said cross head being formed with horizontal and vertical slots, notched plow shanks disposed in said slots, said cross head being formed with longitudinal slots communicating with said first mentioned slots, and spring latches pivotally connected to said cross head, each of said latches being adapted to fit in one of the longitudinal slots and engage the notched edges of the plow shanks, as and for the purpose described.

2. A device of the character described comprising a beam, a cross head secured in termediate of its ends to said beam, said cross head being formed with slots, plow shanks disposed in said slots, said cross head being formed with longitudinal slots communicating with said first mentioned slots, and spring latches pivotally secured to said cross head, each of said latcheshaving an inwardly projecting flange adapted to fitin one of the longitudinal slots and engage the notched end of one of the plow shanks, as and for the purpose described.

3. The combination with a gang beam and notched plow shanks, of a cultivator crosshead formed with transverse slots to receive the plow shanks and having longitudinal slots communicating with said transverse slots and spring latches each pivotally secured at its inner end to the cross head and each provided with an inwardly projecting flange, said flange being adapted to fit within one of the longitudinal slots and engage the notched edge of one of the plow shanks, the latches being removably secured at their free ends to the ends of the cross head.

4:. A device of the character described comprising a beam, a cross head secured to said beam, notched plow shanks, said cross head being formed with transverse slots to receive said plow shanks, the cross head being also formed with longitudinal slots communicating with said transverse slots, and spring latches having longitudinal inwardly projecting flanges adapted to extend within said longitudinal slots and engage said notched shanks, to hold said shanks within the transverse slots, as and for the purpose described.

5. A device of the class described comprising a beam, a cross head secured intermediate of its ends to said beam, horizontal slots formed in said beam on one side of its pivotal point, vertical slots formed in said beam on the other side of its pivotal point, plow shanks disposed within said slots, said cross head being also formed with longitudinal slots communicating with said vertical and horizontal slots, and spring latches pivotally secured to said cross head and adapted to extend within said longitudinal slots to engage said notched shanks, to hold said shanks within said vertical and horizontal slots, as and for the purpose described.

In testimony whereof I hereunto atfix my signature in the presence or" two witnesses.
